You guys using timelapse take a photo every 2 seconds? Or faster? I just recently acquired a hero 3+ black and taking it to vanuatu in a week to play around with.

Super duper late reply, depends on how long you are doing your time-lapse. For example, my time-lapse above (morning daily route) was only about a 15mins drive, so I did it in every 2seconds, or else it would've looked funny and a very short video as well.
